Industrial 8-Ch Analog Input Extender Module
- แบรนด์ WaveShare รหัสสินค้า: CA-8CH-AN-EXT
MODBUS RTU Analog Input 8CH is an industrial standard analog acquisition module, that supports multiple ranges and 8-channel simultaneous acquisition, with built-in protection circuits such as power isolation, magnetical isolation, resettable fuse, and TVS.
Modbus RTU Analog Input 8CH (B)
Supports four ranges (configurable):
0~10V (default)/2~10V
0~20mA /4~20mA
Primary Function
Supports Sending Modbus RTU Protocol Commands Via RS485
To Acquire Data From 0~20mA/0~10V Sensor
Industrial Grade Isolated Protection
Onboard power and signal dual isolation for RS485 communication, provides stable isolation voltage, features high reliability, and strong anti-interference performance. Built-in TVS (transient voltage suppression tube) can effectively suppress the surge voltage and transient peak voltage in the circuit, lightning proof & ESD protection. Built-in resettable fuse and protection diode to ensure stable current and voltage output, provides over-current and over-voltage proof, improves shock-proof performance, suitable for industrial environments with high requirements.
Supports Voltage/ Current Acquisition
